Feit known that. LTionns H. SPRINGER, a" citizen of the United States, residing at Phila.- delphio, in the county ,of Philadelphia vand State-of Pennsylvania,'have invented certain new and" useful Im p'rovementsn Scum orDirt Arresters for Centrifugal Separatore; of which v 'the following isispeoiiication. 7

The invention relates to scum o 'ridiit `.firrosters for centrifugal separators. f

The object is to produce a. device by'which clogging 'or' choking, by deposit and accumuvented anda iioiv oflliquidftherethroug'h maintained contiuuousyb'- being rendered, free and unobstructed. j

With this object in fview, the invention con siets in certain -novel cousti-notions. and arrangements of parts to'sbe hereinafter de-V In the accompanyingdrawings, forming' -cete corresponding parts in the severalviews.

Iniheuse of maehines-'fofthis vc lase,it is: Well-,known that `the accumulation Yis. mainlyV "at the bottom, around) the inner ,wall 'of Y the ball nests and revolves; third, steel ball on which the weight of both-'spindles yeind the bowl rests fourth, steelfpinin Ytheltn vverjend of the 1 lovyer' Spindle] that rests ou the bell; "fifth,v bush tothe lower hering 'for the lower. spindle; sixth,'oil tubewhere vtlievraete oil 'isdisy charged (lower oiltube); seventh', lower spin- Fri-CE;

which, in its pi'efei'redform,consists of a. baud theinnerwall of th'ebowl, as to forni an'a'ch .95

over or eroundthe inlet ends ofthe skim milk exit .tubes andV thereby serve' a's--a deflector,

shieldv or arrester in preventing deposit aindf bowl, where it, becomgeea'lsolidlypaelted mass.' 1

The feed being downward from the top of this bov'vl, the new milla is et once caught by the whirling liquid within the bowl, and thereupon, the contained foreign substanceV 'ce' comes immediately separe-ted and forced outwerd again st the well of of the peculiar slope of the bowl By reason this well, also owing to the action 'of gravity, this eubetence isl of this deposited cumulus, and to effect this,

- may be run for e.

the metal bendfroni which each arrester is made, is'of n. Width suficient to extend from the well of the bowl inward beyond tbe inlet end' of the skim milk tube, it being. reduced .in width, centrally, to allow for the free entrance of mili; into the exit tube. Asefurther protection against the entrence ci foreign substance in or neer the inlet ende of the skim milk tubes, bendmey, if found desirable, be turned up form e'ange,

The curve of the arch may be varied to-suit the requirements of machines ofdiiferent ecnstruction, as it will be et once obvious,- that tubesvarying in diameter will require e corresponding Variation in the form of arresten' At times, it may also be desirabieto employ a band of greater length, in constructing the errestenso that the extremities can bo turned inward against the exit tube, es is clearly shown in; Figs. 3 end 4, and tile detail views thereof. l

"Prominent among tbe many end-importent eldventages of. this invention tney be men4 tioned, its'extreme simplicity oflconetruction,

it being formed from a 'plein rectangular strip or bandof metal, which may be readily bent by band to the proper curve, and therefore, does not require to be hammered, pressed or stamped into shape, except for "the iienge at the inner edge, whichmay be dispensed with when desired. Further, in maintaining the output constant end continuons, the nie-chine much greater length of time without necessitating e. thorough washing, as i is now required after two or three hours run; and further, in preventing def-osit and nccuf rnulation at the inlet end of the skim milk exit tubes, the capacity of the machine 'is I claim as new isthe inner edge of tbev :senseo thereby increased, as has been demonstrated 'oy actuel tests,

Having fully described my invention, what 6 a l, The combination with e liquid separator, of e. scum'and dirt arrester formed by archinge bend oristrip around the inlet end of the outlet pipe o the bowl of the separe-iter, tliewidtb ci the eend being reduced centrally, for the purpose described,
